Specific implementation mode
Embodiment one：
As Figure 1-Figure 4, Novel bridge frame connection structure, including 2 crane span structures, this 13, the both sides of the crane span structure 13 are set respectively
Fixed plate, fixed plate can adopt punching press and be made to be an integral structure with crane span structure, can also use split structure.In each fixation
Two rows rectangle mounting hole is provided on plate, often row can be multiple, such as 2,3 etc..The both ends docking of straight-through crane span structure 13,
The inside of crane span structure docking is equipped with interior connecting plate 2, and punching stretch has two rows arcuate receptacle on interior connecting plate 1, the quantity often arranged
It is equal with the quantity on two docking crane span structure mounting plates.The upper arch of upper row insert 10 mouthfuls of arcuate receptacles 11 in lower row just on
Side, and upper and lower two rows of arcuate receptacle is respectively on two center lines.Set on plate it is spaced be equipped with 4 it is fond of gossip, with arch
Shape socket matches.Fond of gossip 6 are equipped with circular arc reinforcing rib 8, the shape one of the shape of the arc-shaped reinforcing rib 8 and the socket
It causes.This programme has as follows a little：(1) four arch tearing notches, elongated arc hook above and below interior connecting plate, right angle crimp structure is by mould
Tool punching stretch is made, and can increase by one times of self-strength or more, while reducing material thickness, reduces steel consumption；(2) on plate
Portion uses circular arc hook structure, and being equipped with 2 boss structures below circular arc hook structure designs, and plate lower part tongue is reinforced using circular arc
Muscle improves plate self-strength 2 times or more；(3) interior connecting plate four arch tearing notch structures and cooperation fond of gossip below plate up and down
Installation can be completed in inserting, quick and easy for installation；(4) arch tearing notch structure omits clear space height, equal with width on interior connecting plate
More than plate circular arc muscle height fond of gossip and tongue width, upper arch tearing notch structure is smoothly initially passed through convenient for plate is fond of gossip, it can be quick
Installation positioning, improves installation speed；(5) arc hook is identical as crane span structure arc hook above plate, installs rear axle stand bridge position straight line
It spends, appearance looks elegant；(6) arc hook stable structure above plate, is tapped indeformable using tool；(7) arc hook above plate
The 1st boss of root reaches opening position above crane span structure, completes installation；(8) end fond of gossip of plate uses the domes of gradual change,
It can make end fond of gossip that can easily enter through the tearing notch structure of interior connecting plate, realize quick inserting function；(9) plate lower end is inserted
The circular arc muscle of tongue makes it have good rigidity, ensures that itself is indeformable during interference fit, promotes interior connecting plate tearing notch
Malformation and its cambered surface are completely close, ensure the intensity of junction.
Plate circular arc reinforcing rib fond of gossip can increase rigidity fond of gossip, and during inserting, deformation fond of gossip is much smaller than interior connection
Arch tearing notch structure deformation, and circular arc reinforcing rib give circular arc camber fond of gossip increase it is fond of gossip with interior connecting plate arch
The contact area of tearing notch structure greatly increases the clamp force and frictional force of connecting plate and plate in folder in interference fit.
The size of the arcuate receptacle 10 of upper row is slightly larger than the size of lower row's arcuate receptacle 11, is smoothly first worn convenient for plate is fond of gossip
Cross arch tearing notch structure.
Embodiment two：
As Figure 1-Figure 4, for the ease of installation, Inner arc hook structure 9, lower end are equipped in the upper end of interior connecting plate
Equipped with right angle crimp 12, the right angle crimp structure of the interior elongated arc hook in connecting plate upper end, lower end has intensity of joint board in enhancing
With the effect of rigidity.It is equipped with external arc hook structure 3 in the upper end of plate, plate circular arc hook structure is increasing plate rigid foundation
On, and match with the arc hook section in crane span structure section, it is tapped convenient for tool indeformable.The root of outer circular arc hook structure 3 to
Two sections of boss structures 4,5 are had, on the one hand two sections of downward boss structures of plate arc hook root increase plate rigidity, separately
On the one hand upside boss does not influence cover board installation after ensureing crane span structure assembly, and downside boss then gives the interference volume of plate outward,
It is set more to fasten in plate assembling process.The interior lower four arches tearing notch structure clear space height of connecting plate is slightly above plate lower end
The circular arc muscle height of tongue, but the lower four arches tearing notch structure clear space width of interior connecting plate is slightly less than the width of plate lower end tongue
Degree, to realize that plate is fond of gossip in the interior connecting plate arch tearing notch of tool percussion insertion, interior lower four tearing notches of connecting plate occur
Interference deforms, and ensure that the tightness of attachment device assembly.
It is described it is fond of gossip be arranged in the lower section of boss structure 4,5, outer surface fond of gossip is equipped with triangular groove texture 7.Plate is fond of gossip
Lower end is equipped with protrusion, rear in connecting plate arch tearing notch structure in insertion to have the function of increasing friction force and retaining.On plate
Square arc hook root be equipped with 2 boss, the 2nd boss plate it is fond of gossip be close on the outside of crane span structure enter interior connecting plate under four arches
When tearing notch, the 2nd boss root reaches crane span structure opening position, and during continuing grafting, the 2nd boss, which enters, to be adjacent on the outside of crane span structure
Meanwhile giving that plate is elastic outward, simultaneously plate tongue is in the portion by four arch tearing notch structures on interior connecting plate
Four arch tearing notches on connecting plate, keep plate more more slotting tighter in the separated stretching outward that begins.To further improve assembly
Tightness；1st boss plays the role of hiding cover board rigging position in bridge cover plate installation process；Plate lower part length is sublingual
End is equipped with bulge-structure, rear in connecting plate arch tearing notch structure in insertion to have the function of retaining.
The installation process of the utility model is as follows：
The first step straight-through 13 is docked two-by-two；
Connecting plate 2 is assemblied in straight-through 13 inside in second step, and 2 arcuate receptacle knot 8,9 of interior connecting plate passes through straight-through hole；
Third step holds plate 1, so that plate 1 fond of gossip 6 is inserted into from straight-through 13 outside and is torn by the upper arch of interior connecting plate 2
Mouth structure 8,16 end fond of gossip circular arc portion of plate enter in the lower arch tearing notch structure 11 of interior connecting plate 2, plate 1 fond of gossip 6
Width, height are respectively less than the upper arch outlet structure 10 of interior connecting plate 2, assemble external institute's spacing size after leading directly to and are slightly larger than
The size of the lower arch outlet structure 11 of interior connecting plate 2；
4th step taps the external arc hook 3 of the top of plate 1 by wooden mallet, make fond of gossip the 6 of plate 1 completely into and pass through
The lower arch outlet structure 11 of interior connecting plate 2 completes assembly.The clamping force source of assembly：1. the lower arch for passing through interior connecting plate 2
Fond of gossip 6 interference fit of tearing notch structure 9 and plate 1 clamps straight-through；2. the lower convex platform 5 of plate 1 is expected by straight-through outside simultaneously
Interference fit outward is generated when thick, when assembly, which changes interference fit, can be transmitted to fond of gossip the 6 of plate 1 and the upper arch of interior connecting plate 2
